I’ve been using this travel adapter for over 10 years. It converts one standard European outlet into two US plugs, but best of all is that it has built-in surge protection. That one time in Ireland when I couldn’t be bothered to dig it out of my bag? That’s when I fried my power supply. Ever since then, this is the only adapter I use when traveling.
I’ve never seen another combination surge protector/travel adapter, and the fact that it gives you two-for-one outlets makes this a fantastic tool.
[Note: The EuroSurge can be adapted for other non-European countries using these Schuko adapters]
